340 Piston and Valve Question

Hello, I have a 340 .030 over and the deck was milled .010 and the pistons are now .025 above deck. Does this present a issue for piston integrity? I'm running a set of factory "0" heads with 2.02 and 1.60 valves, what would be the recommended head gasket to achieve proper clearances? Thanks in advance for any help.


That’s better than most are. They SHOULD be above the deck. Gasket thickness will be determined by what compression ratio you need or want.

The only way to know for sure what the CR is is to do a 1/2 down fill, CC the heads. And then don’t let me do the math! You need to measure everything and not guess.
